Forward suspension bracket

General information

Forward suspension bracket

1 — an amortization rack
2 — a screw spring
3 — the gas-filled shock-absorber
4 — the stabilizer cross-section
stability
5 — a stabilizer bar

6 — steering draft
7 — a beam of a forward suspension bracket
8 — the steering mechanism
9 — draft
10 — the lever of a cross-section suspension bracket

The independent suspension bracket of forward wheels on double levers, aluminum, has a beam connected with a body through rubber support. The forward beam via cross-section levers and drafts is connected with rotary support. The hydraulic opiraniye of cross-section levers provides compensation of fluctuations even at not balanced wheels. The amortization racks connected with a body and rotary levers by bolts, consist of a screw spring and the gas-filled shock-absorber in the form of a double pipe. The stabilizer of cross-section stability counteracts a body inclination on turns and promotes the best contact of forward wheels to the road.

Carrying out welding and leveling works of a forward suspension bracket is not allowed.

As the suspension bracket is executed completely from aluminum, it is necessary to observe the following:

   a) Contact of a suspension bracket to electrolit of the storage battery is not allowed.
   b) It is necessary to apply to cleaning of a suspension bracket only a brush from stainless steel. It is impossible to apply brushes from steel or brass.
   c) When polishing / разрезке elements of a suspension bracket are necessary for closing for protection against hit of sparks. To subject them to influence of a stream of sparks it is not allowed.
   d) Do not subject elements to a suspension bracket to influence of welding sparks. Close suspension bracket elements.
   e) Do not subject suspension bracket elements to influence in temperature above + 80°С. Influence of temperature of the painting chamber is admissible.
